Objectives: The purpose of this study was to investigate the change in the posture of dental hygiene students and clinical dental hygienists when implementing dental scaling before and after posture correction training using the rapid upper limb assessment (RULA) method and 3D motion analysis. Methods: Thirty-two healthy volunteers performed dental scaling to remove artificial calculus on dental manikin. The movement and angle of the joints were verified by RULA and 3D motion analysis during the procedure. The subjects were also photographed for 1 minute during the procedure for 10 minutes while the calculus was removed. After the removal of the calculus, the subject and the instructor checked the video together. Posture correction training was conducted by the instructor so that the subject could perform the calculus removal operation in the correct posture. Artificial calculus of the adjacent teeth was then removed for the same period of time, and the change in posture was reviewed. Results: The total score of the posture change using RULA was 5.72 ± 0.58 before training and 4.31 ± 0.10 after training, showing a significant decrease after training (p<0.001), and upper arm, lower arm, wrist position, neck and waist position showed significant decrease after training. The three-dimensional motion analysis showed significant differences according to the criteria measured at all measurement sites except the left shoulder (p<0.05) Conclusions: It was confirmed through RULA and 3D motion analysis that postural correction training using calculus removal images was effective, and that correct postural education is essential to preventing musculoskeletal diseases caused by removal of calculus.

Background: Investigation in gender differences of kinetics and kinematics for individuals with patellar femoral pain syndrome (PFPS) was not sufficiently performed. Objects: The purpose of this study is that whether there is a difference depending on gender from muscle activity and strength and knee valgus angle during controlled single-leg squat which is widely used as clinical movement test for the patient with PFPS. Methods: 20 young adults (10 men, 20.0±2.1 years; 10 women, 20.4±2.1 years) with PFPS were voluntarily recruited in this study. Muscle activity and strength and knee valgus angle were collected during single-leg squat. Independent t-test and Mann-Whitney test were used to compare the differences between groups of male and female. Results: Rectus femoris (t=-2.204, p=.041) and vastus medialis oblique (t=-2.151, p=.045) muscle activity of women were significantly higher than male group. Normalized muscle strength of hip and knee muscles showed a significant difference between men and women (p<.05). Valgus angle of the knee in women (t=-2.450, p=.025) were increased significantly than men. Conclusion: The therapist would consider the characteristics of these gender differences during performing movement test, exercise, and education for the individuals with PFPS.

Lumbopelvic stabilization exercise has become the most popular treatment method in lumbar rehabilitation since its effectiveness was shown in some aspects of pain and disability. The abdominal drawing-in maneuver (ADIM) has been extensively implemented to promote lumbopelvic stability. However, performing ADIM correctly is difficult even for healthy subjects, and it is time consuming to train people in ADIM. Thus, the purpose of this study was to compare abdominal muscle [rectus abdominalis (RA), external oblique (EO), and transverse abdominis/internal oblique (TrA/IO)] activity during lumbopelvic stabilization exercises (ADIM only, ADIM with a ball, maximum exhalation only, and maximum exhalation with a ball) performed in a supine position with feet against a wall. Fifteen healthy subjects were recruited for this study. Surface electromyography was used to measure abdominal muscle activity during lumbopelvic stabilization exercises. A one-way repeated-measures analysis of variance was used to determine the statistical significance of RA, EO, and TrA/IO muscle activity during four lumbopelvic stabilization exercises. Both-side TrA/IO muscle activity was significantly greater with maximum exhalation with a ball than with ADIM only or ADIM with a ball (p<.008). The results of this study suggest that maximum exhalation with a ball can be used as an effective lumbopelvic stabilization exercise to increase TrA/IO muscle activity in healthy subjects.

Kang-hee Kim,Yoon-hee Ko,윤태림 한국전문물리치료학회 2020 한국전문물리치료학회지 Vol.27 No.4

Background: Because a forward-leaning posture can cause increased back muscle activity and pain. Therefore, an innovative method to reduce back muscle activity and pain is required. Objects: This study aimed to investigate the effects of a head support on muscle activity and pain in a forward-leaning posture. Methods: A total of 14 male and 16 female students (average age, 21.65 ± 2.37 years; height, 166.15 ± 7.90 cm; and weight, 60.65 ± 9.00 kg) were recruited for the experiment. Two of them were excluded due to musculoskeletal disorders. The muscle activity and pain in the forward-leaning posture were assessed while participants washed dishes for 7 minutes with and without a head support. The condition of using a head support was randomly performed with a 5-minutes break. To confirm a lumbar flexion angle of 30° during the experiment, myoVIDEO was used, and surface electromyography was used to measure muscle activity. Pain was assessed using a 10-point visual analog scale (VAS). The Wilcoxon signed-rank test was used to analyze the data, with p < 0.05 indicating statistical significance. Results: The cervical, thoracic, and lumbar erector spinae muscle activities significantly decreased with the use of the head support, but there was no significant change in the gluteus maximus. There was a significant decrease in the VAS score for the lumbar erector spinae (p < 0.05), but there was no significant change in the VAS score for the cervical region. Conclusion: The use of a head support in a forward-leaning posture reduced cervical, thoracic, and lumbar erector muscle activity and pain. Therefore, it could be recommended during working in a forward-leaning posture, such as during dishwashing, cooking, and working as a factory employee.

Background: To evaluate whether extracorporeal shock wave therapy (ESWT) in the pain point is a more effective treatment than the trigger point for myofascial pain syndrome (MPS) of the upper trapezius. Objects: The purpose of this study was to compare the most effective areas when applying extracorporeal shock wave therapy. Methods: A total of 30 patients with MPS were randomly assigned to the trigger point in the ESWT (n = 15) and pain point ESWT (n = 15) groups. Interventions in both groups were performed in one session, i.e., 2,000 shocks with 1.5 bar intensity. Pain and function were assessed using the visual analog scale (VAS) and cervical range of motion (ROM) and based on mechanical muscle properties. Statistical analysis was performed using the repeated measures two-way analysis of variance to determine the significance probability between pre- and post-test. Results: Changes in mechanical muscle properties were not statistically significant between the two groups. However, VAS and cervical ROM showed statistically significant differences at pre- and post-intervention, regardless of the group (p < 0.05). Conclusion: Although no significant difference was observed in the intervention effect, applying an extracorporeal shock wave to the pain point rather than the pain trigger point should be considered in order to save time in effectively and accurately identifying the pain trigger point and site.

Background: The market for vitamin drinks is expanding both in Korea and worldwide. However, it was difficult to find studies regarding the possibility of tooth erosion induction due to vitamin drinks. The purpose of the present in vitro study was to evaluate the effect of tooth erosion caused by a few commercial vitamin beverages on bovine teeth enamel in terms of erosion depth and fluorescence loss. Methods: Three experimental groups (vitamin drinks), a positive control group (Coca-Cola), and a negative control group (mineral water) were established. Each group consisted of 5 specimens obtained from sound bovine teeth. The pH and titratable acidity of beverages were measured. Specimens were immersed in the beverages and artificial saliva for 6 and 18 hours, respectively. This cycle was repeated for 5 days. The depth of the tooth loss caused by tooth erosion (erosion depth) and maximum loss of fluorescence (Max ΔF) were measured using the microscope and quantified light-induced fluorescence-digital, respectively. For the statistical analysis, the Kruskal–Wallis test and ANOVA were used to compare the erosion depth and Max ΔF of the enamel surfaces. In addition, Spearman correlations were estimated. Results: The pH of the three vitamin beverages ranged from 2.65 to 3.01, which is similar to that of the positive control group. All beverages, except mineral water, had sugar and acidic ingredients. Vitamin drinks and the positive control, Coca-Cola, caused tooth erosion lesions, and showed significant differences in erosion depth compared to mineral water (p<0.05). The vitamin beverages with low pH were associated with high erosion depth and Max ΔF. Conclusion: Vitamin drinks have the potential to cause tooth erosion.

The aim of this study was to investigate the effect of hip external rotation angle on pelvis and lower limb muscle activity during prone hip extension. Sixteen healthy men were recruited for this study. Each subject performed an abdominal drawing-in maneuver (ADIM) in a prone position, and extended the dominant hip at three different hip external rotation angles (0°, 20°, 40°) with a 30° hip joint abduction. Activity of the gluteus maximus (G Max), gluteus medius (G Med), and hamstring (HAM) and the G Max/HAM and G Med/HAM ratios were determined with surface electromyography (EMG). The EMG signal was normalized to 100% maximum voluntary isometric contractions (MVICs) and expressed as %MVIC. Data were analyzed by one-way repeated analysis of variance (alpha level=.05) and the Bonferroni post hoc test. Significant differences in G Max and G Med muscle activity were noted among the three different hip external rotation angles. G Max muscle activity increased significantly at both 40° (p=.006) and 20° (p=.010) compared to a 0° hip external rotation angle. G Med muscle activity increased significantly at 20° (p=.013) compared to a 40° hip external rotation angle. The G Max/HAM activity ratio increased significantly at both 40° (p=.004) and 20° (p=.014) compared to a 0° hip external rotation angle. The G Med/HAM activity ratio increased significantly at 20° (p=.013) compared to a 40° hip external rotation angle. In conclusion, 40° and 20° hip external rotation angles are recommended to increase G Max activity, and 20° hip external rotation is advocated to enhance G Med muscle activity during prone hip extension with ADIM and 30° hip abduction in healthy subjects.

이 연구의 목적은 임상에서 뇌졸중 환자를 치료시 앉은 자세에서의 균형을 평가하기 위한 안정적이고 신뢰할 수 있는 평가 방법이 무엇인지 알아내는 것입니다. 널리 사용되는 5가지 앉은 자세에서의 균형평가중에서, 기능적 앉기 검사(Function in Sitting Test), 트렁크 손상 척도 (Trunk Impairment Scale), 앉은 균형검사(Sitting Balance Scale)은 뇌졸중 환자에게 적용시 매우 우수한 신뢰도와 좋음에서 매우 우수한 정도의 타당도를 보여줬다. 일반적인 상황에서 뇌졸중 환자의 앉은 균형을 측정할 때 이 도구들을 유용하게 사용하는 것이 좋습니다. 수정된 리치 테스트(Modified Functional Reach Test)는 간단한 측정 방법과 우수한 측정자내 신뢰도를 보여 주지만 중간 정도의 타당도를 보여 주었습니다. 따라서 간편한 측정이 요구되는 사항에서 Modified Functional Reach Test의 사용을 고려하는 것이 좋겠습니다. 트렁크 조절 검사(Trunk Control Test)는 상대적으로 다른 측정 도구에 비해 신뢰도와 타당도가 떨어져서 검사의 효용성/정확성이 떨어졌다. 임상가는 앉은 자세 평가 도구들이 각자 고유한 특성을 가지는 것을 이해하고 상황에 따라 유용하게 사용하는 것을 추천합니다.

韓國人의 法意識

Bringing a suit to court, whether it is civil or criminal is believed by Korean as an unfavorable matter. Most of the cases are solved rather by compromise between two persons concerned than by law. Roman people were proud of their law-abiding and regulated by law. But Korean prefer humanistic decision to strict law itself. If judges make decision by only law they are thought as unhumanistic judges. The contents of insurance contract which is influenced by Western law are written in very detail because they expect and ready for so many accidents. Western people don't like to solute case by case. We esteem more loyalty than written contracts. Contrary to Korean, Jewish Concept of donation for God is strict and rigid. We haute saying mine is my own and fours is also mine. Borrowing and using agricultural instruments without possessor's agreement is prevalent in rural country. We want unanimous consensus in voting, But Jew think it is only possible by bias, exciting or pressures. These kind of war of thinking come from agricultural culture. Agriculture requires year long settlements. Stock farming race move whenever they need. Agricultural people think his idea is same with others. They are not individualistic. They esteem more group mind, group decision. Western Culture comes from fight whereas Oriental one through harmony. The human relation are becoming more and more complex. We can not ignore Western style of law concept.
